Detailed Description
The SoPointLightManip class is used to manipulate point light nodes.
A manipulator is used by replacing the node you want to edit in the graph with the manipulator. Draggers
are used to to manipulate the node. When manipulation is finished, the node is put back into the graph,
replacing the manipulator.
Constructor & Destructor Documentation
SoPointLightManip::SoPointLightManip (void)
The constructor. Creates a default dragger.
SoPointLightManip::~SoPointLightManip (void) [protected], [virtual]
The destructor.
Member Function Documentation
SoType SoPointLightManip::getTypeId (void) const [virtual]
Returns the type identification of an object derived from a class inheriting SoBase. This is used for
run-time type checking and 'downward' casting. Usage example:
void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or
others: this method needs to be overridden in all subclasses. This is typically done as part of setting
up the full type system for extension classes, which is usually accomplished by using the pre-defined
macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and
SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.
For more information on writing Coin extensions, see the class documentation of the toplevel superclasses
for the various class groups.
Reimplemented from SoPointLight.
const SoFieldData * SoPointLightManip::getFieldData (void) const [protected], [virtual]
Returns a pointer to the class-wide field data storage object for this instance. If no fields are
present, returns NULL.
Reimplemented from SoPointLight.
SoDragger * SoPointLightManip::getDragger (void)
Returns the current dragger.

setDragger()
SbBool SoPointLightManip::replaceNode (SoPath *path)
Replaces the node specified by path with this manipulator. The manipulator will copy the field data from
the node, to make it affect the state in the same way as the node.
SbBool SoPointLightManip::replaceManip (SoPath *path, SoPointLight *newone) const
Replaces this manipulator from the position specified by path with newnode. If newnode is NULL, an
SoPointLight will be created for you.
void SoPointLightManip::doAction (SoAction *action) [virtual]
This function performs the typical operation of a node for any action.
Reimplemented from SoNode.
void SoPointLightManip::callback (SoCallbackAction *action) [virtual]
Action method for SoCallbackAction.
Simply updates the state according to how the node behaves for the render action, so the application
programmer can use the SoCallbackAction for extracting information about the scene graph.
Reimplemented from SoLight.
void SoPointLightManip::GLRender (SoGLRenderAction *action) [virtual]
Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants
to throw geometry primitives at OpenGL overrides this method.
Reimplemented from SoPointLight.
void SoPointLightManip::getBoundingBox (SoGetBoundingBoxAction *action) [virtual]
Action method for the SoGetBoundingBoxAction.
Calculates bounding box and center coordinates for node and modifies the values of the action to
encompass the bounding box for this node and to shift the center point for the scene more towards the one
for this node.
Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change
the relevant state variables.
Reimplemented from SoNode.
void SoPointLightManip::getMatrix (SoGetMatrixAction *action) [virtual]
Action method for SoGetMatrixAction.
Updates action by accumulating with the transformation matrix of this node (if any).
Reimplemented from SoNode.
void SoPointLightManip::handleEvent (SoHandleEventAction *action) [virtual]
Action method for SoHandleEventAction.
Inspects the event data from action, and processes it if it is something which this node should react to.
Nodes influencing relevant state variables for how event handling is done also overrides this method.
Reimplemented from SoNode.
void SoPointLightManip::pick (SoPickAction *action) [virtual]
Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
void SoPointLightManip::search (SoSearchAction *action) [virtual]
Action method for SoSearchAction.
Compares the search criteria from the action to see if this node is a match. Searching is done by
matching up all criteria set up in the SoSearchAction -- if any of the requested criteria is a miss, the
search is not deemed successful for the node.

SoSearchAction
Reimplemented from SoNode.
SoChildList * SoPointLightManip::getChildren (void) const [virtual]
Returns the children of this node. This node only has the dragger as a child.
Reimplemented from SoNode.
void SoPointLightManip::setDragger (SoDragger *newdragger) [protected]
The method can be used to replace the dragger with your own dragger.
void SoPointLightManip::copyContents (const SoFieldContainer *from, SbBoolcopyconnections) [protected],
[virtual]
Makes a deep copy of all data of from into this instance, except external scenegraph references if
copyconnections is FALSE.
This is the method that should be overridden by extension node / engine / dragger / whatever subclasses
which needs to account for internal data that are not handled automatically.
For copying nodes from application code, you should not invoke this function directly, but rather call
the SoNode::copy() function:
SoNode * mynewnode = templatenode->copy();
The same also goes for engines.
Make sure that when you override the copyContents() method in your extension class that you also make it
call upwards to it's parent superclass in the inheritance hierarchy, as copyContents() in for instance
SoNode and SoFieldContainer does important work. It should go something like this:
void
MyCoinExtensionNode::copyContents(const SoFieldContainer * from,
SbBool copyconnections)
{
// let parent superclasses do their thing (copy fields, copy
// instance name, etc etc)
SoNode::copyContents(from, copyconnections);
// [..then copy internal data..]
}
Reimplemented from SoNode.
void SoPointLightManip::transferFieldValues (const SoPointLight *from, SoPointLight *to) [static],
[protected]
This API member is considered internal to the library, as it is not likely to be of interest to the
application programmer. Copies field values.
void SoPointLightManip::valueChangedCB (void *m, SoDragger *dragger) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of interest to the
application programmer.
void SoPointLightManip::fieldSensorCB (void *m, SoSensor *d) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of interest to the
application programmer.
